CONDITIONING YOUR AIR CONDITIONER

A central air conditioning system can provide years of satisfactory cooling with relatively little maintenance. However, a seasonal start-up check and periodic maintenance is recommended.

Homeowner Checklist

The amount of do-it-yourself air conditioning maintenance a homeowner can do is limited. However, there are a few steps that can help the system operate trouble-free and minimize the potential for consequential damage. Ensuring adequate airflow is perhaps the most important homeowner responsibility.

Keep shrubs and other plant growth that might obstruct airflow at least 18 inches away from the condenser.

Maintain insulation on ductwork in attics and other unconditioned areas.

Check the condensate drain for any sign of blockage or leakage. Water should be dripping from the end of this drain line when the unit is running. If no dripping is noted, check at the indoor unit for any signs of leakage.

Keep room input and return registers clear of furniture or other obstructions.

Selecting Trained Professionals

If your air conditioner needs more than the regular maintenance described here, consult a qualified air conditioning technician. A well-trained professional can provide a thorough pre-season or maintenance evaluation and servicing as needed. Insufficiently trained service technicians forsake proper diagnostic procedures and often only perform stop-gap measures to keep a unit going. Such short-sightedness can have a drastic effect on other components leading to consequential failure of the entire system.
